row elimination problem.

Hey

I have a matrix A of 34x2 double.

I want to eliminate the rows wherein the value of both the columns is 0.

Answer 1

[madhan ravi]

 A(all(A == 0, 2), :) = [ ]

[Anurag Gupta]

it is not returning me a A as a matrix, it is getting converted to a vector.

[madhan ravi]

What?

>> A = [1,2; 0,0]
   A(all(A == 0, 2), :) = [ ]

A =

     1     2
     0     0


A =

     1     2

>>

Hello Madhan,

Extremely sorry I actually made an error earlier in the loop which lead to me not getting the right answer. Thanks a lot for the solution. It worked perfectly.

Regards,

Anurag Gupta
